I'm assuming without ZordsYeah, but if you want to speculate both with and without then that's cool. The Zords give them a pretty significant advantage that would give them an edge against heroes they couldn't defeat on foot.
Maybe Wolverine?
I dunno, kinda hard to say. Aren't the puddies like pretty strong compared to a normal human? They burst into rock fragments when they die, so the Rangers are pretty strong.
I feel like we're all underestimating them. There was a storyline where an alternate Tommy took over the world.I don't think he did that with just his abilities. Zords and Rita's resources did a lot of the conquering.

I feel like they could do a little better than just street level.
